It doesn't even have to be a discussion, per se. One common fixture in old-school community forums are participation topics -- open-ended, low-effort topics like "what music are you listening to" or "what did you have for lunch today" that can give people a low-commitment way to be active in a community. Link-centered forums like HN or Reddit don't handle this well.
